What do you do with this power if solar and wind are cheaper? I.e. in a free market, what if buyers prefer wind and solar energy? Do you dump the energy at a loss, go bankrupt leaving investors and banks to write off the cost?
Why would anyone take that risk?
Is there anyone willing to build such a powerplant at fixed cost? (i.e. after x billion euro you either get the plant or your money back)
Obviously, the situation will change if hit the wall with wind and solar. But there are no reliable predictions if or when we would hit a wall.
That seems unlikely. If, for example, you run at a loss 50% for the time, then you need to have extra expensive rates during the other 50% of the time. Based on typical construction costs of nuclear power plants, those high rates are extremely attractive for competition from wind and solar. Which will reduce the amount of power that can be sold at premium rates, which requires even higher rates to compensate, etc.
Basically, in a free market, nuclear power is competing with power from batteries, hydrogen, and other ways of storing electricity.
This is an extremely unattractive market for nuclear.
